Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pallet loading device for a vehicle that is capable of checking the brake condition of a vehicle.

[Prior Art] A conventional vehicle pallet loading device will be explained with reference to FIG. 16. A vehicle d is loaded onto a vehicle pallet c on a drive roller conveyor b which is horizontally supported by a vertically movable lifter a. When the driver of vehicle d stops at a predetermined position and confirms that the position of the tires of vehicle d is at the specified position using photoelectric switch e for confirming the position, the driver of vehicle d operates the brakes and gears of vehicle d. After the vehicle d is prevented from moving on the vehicle pallet c, the vehicle d is disembarked from the vehicle. In the figure, g is a movable stopper for fixing the vehicle pallet c, and f is a conveyor.

[Problems to be Solved by the Invention] However, in the above-mentioned vehicle pallet loading device, even if the driver of the vehicle d forgets to operate the brake or gear and gets off the vehicle, the drive roller conveyor Since the vehicle d is supported horizontally, a phenomenon such as the vehicle d moving on the vehicle pallet c does not occur on the drive roller conveyor b, so an alarm device (not shown) is activated. Therefore, even the vehicle pallet c carrying the vehicle d whose brakes are not applied is conveyed as is to the downstream conveyor f.

The vehicle d on the pallet c transported to and after the conveyor f moves on the vehicle pallet c during the transport line or during cargo handling with the stacker crane, causing abnormalities in the appearance of the cargo, which can lead to various troubles. There are problems such as causes.

In view of the above-mentioned circumstances, the present invention has been developed by adding a mechanism that can check the braking condition of the vehicle to the pallet loading device for vehicles, thereby making it possible to prevent troubles on the conveyance line and improve the operating rate of equipment and work efficiency. This was done with the aim of improving safety.

[Means for Solving the Problems] In the present invention, a pallet loading device for a vehicle includes a link mechanism for integrally tilting a pallet for a vehicle and a drive roller conveyor that conveys the pallet for a vehicle, and a link mechanism for integrally tilting the drive roller conveyor. A vehicle overhang detection sensor is installed on the tilting hinge side.

[Operation] Therefore, in the present invention, before the vehicle pallet carrying the vehicle starts to be conveyed toward the downstream conveyance line, the drive roller conveyor and the vehicle pallet are tilted by the link mechanism, and at this time, the vehicle pallet is tilted by the link mechanism. If the vehicle's brakes are not operated properly, the vehicle will move backwards due to its own weight, so by detecting this phenomenon with the vehicle overhang detection sensor, the appropriateness of the vehicle's brake operation can be checked and the brakes can be corrected. This also makes it possible to prevent trouble from occurring.
